CCR Data Screens
- Primary data screen
-
Displays the main dive data, including your breathing gas, partial pressure of oxygen (PO2) level, and rate of ascent. You can edit one of the data fields.
Your nitrogen (N2) and helium (He) tissue load level.
Segment 1: 0 to 79% tissue load.
Segment 2: 80 to 99% tissue load.
When you start a safety stop, the safety stop gauge appears (Performing a Safety Stop).
When your tissue load level reaches or exceeds 100%, the decompression stop gauge appears (Performing a Decompression Stop).
Your rate of ascent.
: Good. Ascent is less than 7.9 m (26 ft.) per minute.
: Moderately high. Ascent is between 7.9 and 10.1 m (26 and 33 ft.) per minute.
and
alternating: Too high. Ascent is greater than 10.1 m (33 ft.) per minute.
- Dive compass
-
Allows you to view the compass and set a directional heading to aid with underwater navigation (Navigating with the Dive Compass).
- Customizable data screen
-
Displays additional dive data and physiological information. You can edit the gauges and two of the data fields (Customizing the Data Screens).
Your central nervous system (CNS) oxygen toxicity level.
Segment 1: 0 to 79% CNS oxygen toxicity.
Segment 2: 80 to 99% CNS oxygen toxicity.
Segment 3: 100% or greater CNS oxygen toxicity.
Your current oxygen toxicity units (OTU).
Segment 1: 0 to 249 OTU.
Segment 2: 250 to 299 OTU.
Segment 3: 300 or greater OTU.
